the apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ ball mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where the shell is 5′ inside diameter and the working diameter is only 4’8″ with the liners in place. ball-rod mills, based on 4″ liners
a ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

mines (wa) 36ft sag mill the number of outer head liners was reduced from 36 to 18 pieces and in doing so reduced the time to replace them by 9 hours at a cost downtime saving of about u$25,000 per hour. in this case the liners sections are 3.5 t each. for smaller mills the liners have to be handled and installed manually, so smaller blocks with
a mill liner that occupies less space allows increased volume within the mill and leads to greater grinding capacity and throughput potential. safer maintenance. 50% lighter and have 50% fewer parts on average when compared to traditional cast steel liners. this results in faster relining and quicker installation, keeping your workers inside a hazardous work environment for a shorter time period.
